CVE-2016-20021
9.8CRITICAL
What is CVE-2016-20021?
A vulnerability exists in Gentoo's Portage package management system that allows executed code to potentially run without proper PGP signature verification. This occurs specifically in the emerge-webrsync operation, which downloads a .gpgsig file but fails to validate its signature. As a result, users may inadvertently execute unverified code, posing a risk to system integrity and security. This vulnerability affects versions of Portage prior to 3.0.47, emphasizing the need for security measures and updates to protect Gentoo environments.
